TYPEJJBITING MACHINE.

' To all whom it may concern citizen of; the United States, residing inBrooklyn, in the county of Kings and State of New York haveinventedcertain new .and useful Improvements in Type-Writing Machines, of whichthe following is a speci- 'ficatiom' 3 English-language.

- or'more characters, which has recently been devisedjfor this purposebycertain aut'horir' ties. [The lettersfor characters forming thisalphabet are not herein 'illustrated,because the machine -is also'adaptedfor writing other 'languagesthan Ghinese-f The machine Provisionis also made for moving is illustrated; as'adapted for writing a singlecase, both capitals and small 1e'tters;:no case shiftin'g'meclianis'mbeinglshown.' f

It is customary in writing ordinary Chinese characters to place'themone'below another, beginning at the top of the. page, the line of writingreads down the page; and this plan will be continued in connection withthe new Chinese alphabet referred to.

This invention provides for the Worksheet to be moved vertically at theoperation of the type-l(eys, so that the alphabet characters willbeivrit'ten onthe work-sheet one below another, the top of each letteror alphabet character being adjacent to the bottom of the next letter oralphabet character,

in contradistinction to theiisual' method of writing letters side byside as in English. the 'work sheet laterally for making spaces betweenthe vertical lines of writing. According to the Chinese custom, thewriting begins at the right-hand inarginof the \vork-she'gt and proceedsline-byline toward the left hand margin. 7 v

In carrying out the invention in its present form,.the worksheet isplaced upona revoluble cylindrical-platen, which extends in a directionat right angles to the line of writing; and at the successii-"c type hestrokes, the platen is caused-t0 rotate to ad for alphabets not provided,withso that showing a part ofthetrainlof gearsiwhi controls therotation of the platen, and a showing a release key for said carriage.Fig-j Specification of Letters Patent. 1 t t d n 1 Applicationfiled.January 13, 1913i Serial'No. 741,609."

The drawings show anUnderwood frontstrike typewriter', which is used forcon-- .venience in illustrating the. invention; said typewriter beinghowever substantially away is prevented from operating said linefeedingdog's. Fig. 8 is a plan of the typeoperating keys and levers, and someofthe' gears w'hich'control the operation of the platen.

Fig. 9 is a rear elevation of the modified for the purposes of theinvention.

Alphabet keys 1 are mounted upon levers 2, fulcrumed at 3 and havingreturning springs 4; the levers having in-andsslot connections at 5 withbell cm s 6, which have pin-and-slot connections at 7 with type bars-8,-carrying alphabet types 9 to swing upwardly and rearwardly to strikeupon the frontside of arevoluble platen 10; the type bars being mountedupon a' curved fulcrum rod 11: The types '9 are intended for writingaforeign language, and correspond with foreign alphabet characters orletters on keys 1, which areillu'strated diagrammatically at: Fig. 8.Theplaten is not made to shift up and down, the machine being intendedfor-use in writing foreign-languages which donot have sets of bothcapital let- 'ters and lower-case letters; but the invention is notlimited to the, use of a single case of types.

The types strike through a ribbon 12, h

which is normally below the printingv point, but which is lifted up atevery type stroke to cover the printing point; there being' for thispurpose heels'13 provlded on the type bars to engage a segmentaluniversal bar 14, which forms'part of a frame 15, that is moun'tedto' bedriven rearwardly by theheels 13 on the type bars 8; said universal barat its rear end having arms 16 pivoted to the upper ends of upstandingarms 17, which are fast to'a rock shaft 18;

-- the front of the universal bar frame 15 being supported in the usualmanner, and

. a spring 19 returning the universal; bar

frame 15 after actuation. Upon this universalbar frame 15 is fixed aslotted actuator 20 to engage a pin 21 upon the ribbon vibrating lever22, which is pivoted at 23 upon the machine frame; said lever 22carryi'ng at its forward end an upright slide 24 to' which is threadedthe ribbon 12; for as the universal bar is driven back the slide orvibrator 24 is thrown up' together with the ribbon, and hence the typesmake inked impressions .upon the Work sheet 25 which is carried aroundthe platen 10.

As each character is printed, the paper is fed up, the platen 10 beingrevolved step-- by-step for-this purpose. This rotary letter orcharacter spacing movement of the I which extends a rock Shaft 32- fastthereto; 0 4

the rocker-31 being confined between ears 33, 34 fixed upon theframework and seiving as bearings .for the rock shaft 32. This shaft iselongated and at its ends is journaled in bearings 35, 36; and it has atits ends a forwardly extendingpair of arms 37, which are connected attheir forward ends by a rod 38,, which forms a second universalba'r, andis pressed by a' spring- 39 up against the under sides of the key levers2. g I

l/Vhenever any key is depressed to operate its type, the universal bar38 is depressed, and the dogs 29, 3Q are vibrated-forwardly;

the escapement wheel 28' not beingl'et off 9 at. this time, but thelimber dog 29 being drawn to the right at Fig.9 by means of a spring 40,so as to be in position to engage the next tooth of the escapement Wheel28.

Uponthe release of the key from pressure 0 after the type impression ismade, the spring 39 returns the universal bar 38 and the dogs 29,30permitting the escapement wheel 28 to advance one step and the spring26 to rotate or drive the platen a corre- 5 sponding distance. I

The train of gearing between t. spring I barrel 27 and the platen maycomprise a bevel gear 41' fixed onthe spring barrel,

a bevel pinion '42 in mesh therewith .and 11a.

mountedupon avertical shaft 43, a-bevel pinion 44 on the upper end ofsaid shaft,- a bevel pinion 45 fixed on a horizontal shaft 46 which isjournaled in the machine frame,l

and a gear 47 fixed upon shaft 46 and meshing with-a long barrel pinion48 which is journaled by means of gudgeons 50 upon brackets 49 fixedupon the machine frame.

This barrel pinion 48 may engage either of two pinions 51,52, both ofwhich are fast 12o upon a horizontal shaft 53 extending from end to endofthe platen frame or carriage 54. By means of intermediate pinions 55,56, the pinions 51, 52 are connected to pinions 57 ,58, fixed upon theaxle 59 of the platen 10, and forming part of the gear train leadingfrom the spring. barrel 27. The platen frame orcarriage 54' is mountedto move endwise for linespacing; and x' 'hen either pinion 51 or 52moves out of mesh aspring 26" ('Fig'.

with thei barrel pinion 48, the other pinion always remains in mesh withpinion 48, so that'a positive connection is maintained be- "tween theplaten and the spring barrel 27 and its escapement devices, and hencethe writing, the operator grasps a'handle 63',

pivoted at 64 on the right-hand side of the machine frame, and throwsthe same downwardly from the dotted-line-position at Fig. 3 to thefull-lineposition at Fig. 5, thereby both rewinding the spring 26 andrevolving the platen 10 backwardly to initial position;

the limber dog 29 beingswiveled at x 65 (Fig. 2) in a] manner common intype- 7 writing machine s,- to permit the backward revolution of theletter-feeding escapement wheel 28. The-handle or arm 63 is con nectedtothe spring barrel 27 by means of a sector166, extending rearwardlyfrom the pivot 64, and meshing with a bevel pinion G7, to which is fixeda pinion 68, meshing with a gear 69 on the spring barrel 27.

It will be seen that the. foregoing alphabet character or letter-feedingmechanism is effective to rotate the platen at every key stroke,regardless of the position of the platen carriage,.so that the writingof vertical lines on the work-sheet may proceed until the: same isfilled.

A non-printing word-spacing key or bar 70*,inay be arranged across themachine in front of the keyboard, and its levers or supports 7O mayextend back parallel with the type-key levers,.and actuate theumversal'bar 38 at every depression of key 70*; and these levers 70 may,if desired, be curved at 7 0 'to clear the bell cranks 6.

After the completion of any vertical line of writing, a key 71 may bepressed back for line-feeding the carriage 54, which slides uponhorizontal rails 72, 73 in the same manner as the paper carriage of saidUnderwood typewriting machine. This key 71 permits the carriage to bedrawn along by a spring barrel 74 (Fig. 9), which is connected by astrap 7 5 to a pm 76 on the carriage; said strap passing over a pulley77 and forming a return loop, so that the spring barrel 74 draws thecarriage from right to left, as seen at Fig. 9. \VllK'll lS a rear view.V'ewed from the froat of the mach ne, the carriage is drawn from left toright at the line-spacing opendimi. This is useful for languages likeChinese and others, where the first vertical line of writing is made atthe right-ham? side of the work-sheet or page, and in which "the secondline of vertical writing is placed at the left of the first 'line ofwriting, and so on until the page is filled. 1

A rack 78 is connected to the carriage to mesh with a pinion 79, towhich is connected an escapement wheel 80, which is controlled by dogs81, 82, which may be constructed and operated in a manner to resemblethe letter-feeding dogs of said Underwood tyilewritin-g .machine, withthe exception that they are not operated by the letterfeeding mechanismof the present machine; the universal bar frame 15 being cut-away as at83' (Fig. 7) to avoid striking these dogs 81,82. p At the completion ofa page of writing, the carriagemay be pressed back to the left,

th'us rewindin'g the spring barrel 74; the

escapement wheel being connected to the pinion 79 by means of pawls 84(as usual in the letter-feeding mechanism of said Underwood machine) topermit right to left movement of the carriage while the escapement wheel80'remains stationary.

, The carriage may be released to be set to different line positions, bydepressing a release key 85.0n the carriage, which is connected' to abail 86 pivoted at; 87 on the carriage and having thereon theline-feeding rack 78, which by depression of the key is lifted from thepinion 79. Said linefeeding key 71 may be mounted on the forward end ofa stem 88, to press rearwardly a lever 89, the latterpivoted at 90 uponthe framework, and at its lower end connected to a link 91, whichextendsrearwardly to an arm 92 pendent from a horizontal rock shaft 93. At itsinner end said rock shaft carries an-upstanding arm 94, which, when thekey 71 is pressed back, engagesthe feeding pawl or dog 82 to press thelatter and the pawl or dog 81 rearwardly; and upon release of said key71, a spring 95 returns the same,

and a spring 96 returns the dogs 81 and 82 I to normal position, thuspermitting the escapenient wheel 80'to feed one step, together with theplaten carriage 54. and thus effect a line-feeding movement of the worksheet 25. By manipulating said key 71, the open ator may make as manyspaces as desired between the vertical lines of writing; or thecarriage-release key may be used for the same purpose. Also dependingfrom the rock shaft 93 is an arm 97, seen best at Fig. 4, which isprovided for enabling the platenrotating arm or handle (33 to effectautomatically a line-feeding movement of the platen carriage. Said arm03, for this purpose. is fast upon a horizontal rock shaft 98, which atits inner and carries an arm or dog 99, to engage a pawl or trip 100,which is pivoted at 101 upon the lower end of said arm 97, and isnormally held by a s .)ri-n g 102 against a stop 103 on said arm 97; thepawl having a shoulder 104 to engage said gages and drives the pawl 100and the arm 97 bodily forward; these parts turning about the shaft 93 asif they were made in v one piece, and causing the arm 94 on said shaftto swing rearwardly to operate the line-feeding dogs 81, 82.

Preferably, before the conclusion of the 'down or driving stroke of thearm 68, the

point of the dog 99 escapes from the pawl 100, so that at any timethereafter the key 71 may be operated to perform its line-feedingfunction wholly independently of the said dog 99 or of the arm 63; thelatter, of course, remaining in itsdepressed position until the typesare again operated andthe .platen rotated for letter-feeding; said arm63 gradually rising during the writing of the next vertical line on thework sheet.

During the return stroke of the arm 63 and the dog 99, the dog engagesand idly rotates the pawl 100 about the pivot 101; and after the dogpasses the pawl, the latter is snapped back to normal position by itsspring 102.

Certain of the type keys, as for instance key 1, are silent, that is,they are capable of printing but incapable of causing the work-sheet tobe character or letter-spaced, these keys being used for accenting orfor building up alphabet characters, or for other purposes. The lever ofeach such silent key 7 is arched upwardly at 70, Fig. 3, to clear thesecond universal bar 38, so that said key lever cannot operate thealphabet character or letter-feeding dogs 29, 30. Its type bar, however,is provided with the usual heel 13 to operate the first universal bar 14which controls the ribbon-vibrating mechanism, so that the ribbon isthrown up to cover the printing point although the paper is not fed.

Variations may be resorted to Within the scope of the invention, andportions of the improvements may be used without others.
